Jerry Sandusky's adopted son, Matt Sandusky, said through his attorney today that he met with prosecutors this week to say for the first time that he is a molestation victim of his adoptive father, the Harrisburg (Pa.) Patriot-News reported .

Matt Sandusky, 33, was adopted as an adult by the former Penn State assistant football coach and his wife, Dottie, after having lived with the family as a foster child. He had denied ever being abused by his adopted father until now, according to the report.

The revelation came after jurors had begun deliberation in the afternoon in Jerry Sandusky's trial on 48 counts of child sex abuse on 10 boys.

“This has been an extremely painful experience for Matt, and he has asked us to convey his request that the media respect his privacy," his attorney, Andrew Shubin, said in a statement. "There will be no further comment.”

Shubin also said Matt Sandusky was prepared to testify truthfully at trial, if he had been called by prosecutors.

In March, The Patriot-News reported that Matt Sandusky had a rocky relationship with his adopted father. His biological mother, Debra Long, told the newspaper that she believed Sandusky had stolen her son from her.

She testified before the grand jury in early 2011 about strange behavior she says she witnessed between her son and Sandusky, the newspaper added.

Matt Sandusky testified to the grand jury, too. But Jerry Sandusky’s attorney, Joe Amendola, said at the time that he was not worried about Matt’s testimony, and that Long was making false allegations because she was angry at the Sandusky family.

During testimony at trial, Victim 4 told jurors that on one occasion when Jerry Sandusky began touching him during a shower, Matt Sandusky was present but left the shower when the assault began.
